Q. What is the main role of oxygen in cellular respiration?
Oxygen plays a vital role in energy production via a system called electron transport chain (ETC), which is an important component of cellular respiration. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.
Q. What is the function of oxygen in cellular respiration quizlet?
What is the role of oxygen in cellular respiration? Oxygen accepts high-energy electrons after they are stripped from glucose. Cellular respiration accomplishes two major processes: (1) it breaks glucose down into smaller molecules, and (2) it harvests the chemical energy released and stores it in ATP molecules.
Q. How is oxygen used during cellular respiration?
Cellular respiration is the process cells use to make energy. Cells in our body combine glucose and oxygen to make ATP and carbon dioxide. Oxygen combines with the electrons and two hydrogen ions to make water. Lastly, the hydrogen ions flow through ATP synthase to make ATP.
Q. Where is the oxygen used in cellular respiration?
mitochondrial membrane
Q. What products are made from cellular respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Q. What is not a product of respiration?
ATP is produced as a byproduct of the process. When one molecule of glucose is broken down, a total of 36 or 38 molecules of ATP can be produced. This is only possible in the presence of oxygen. Oxygen is not the product of respiration.
Q. Which best describes the end products of aerobic respiration?
Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy. The product of respiration is a molecule called adenosine triphosphate (ATP), which uses the energy stored in its phosphate bonds to power chemical reactions.
Q. What are the products of aerobic respiration in humans?
Here, the glucose and oxygen take part in a chemical reaction. The reaction is called aerobic respiration, and it produces energy which transfers to the cells. Aerobic respiration makes two waste products:carbon dioxide and water.
Q. What are disadvantages of cellular respiration?
Cards
| Term Function Of glycolysis | Definition Breaks down sugar in to pyruvic acid |
|---|---|
| Term Disadvantages of cellular respiration | Definition requires oxygen |
| Term Lactic Acid fermentation | Definition produced in your muscles when there is not enough oxygen present |
Q. What best describes the difference between anaerobic and aerobic respiration?
Solution: Aerobic: Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. (glucose + oxygen -> carbon dioxide + water). Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.
Q. What are the key differences between aerobic and anaerobic respiration?
Aerobic respiration needs oxygen to occur, while anaerobic does not. This presence of oxygen determines what products will be created. During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created.
